摘　　要：青海部分地区线路走廊紧张,为满足不断增长的用电负荷需求,需对现有输电线路进行改造。通过青海某线路改造工程中采用新型耐热导线和大截面导线2种方案的比较,以及2种方案中导线电气参数计算及经济效益分析,证明该工程中采用耐热导线可以取得较大的经济效益,为以后实际工程应用提供了参考依据。The space for power transmission line corridors in some regions in the Qinghai province is limited, the improvements on the existing power transmission lines are needed to meet the increasing power demand. Based on the comparison between the scheme using new heat resistance conductor and the scheme using great section conductor in a power transmission line project, the conductor＇ s electric parameters calculation and economical benefit analysis, this paper demonstrates that using the heat resistance conductor can gain better economical benefit.
